Leners Patent No. 89,177, dazed April 2o, 1869.

IMPROVED SHIPPING-APPARATS IE'OR.V METAL-PLANERS.

The Schedule referred to in these Letters Patent and making part of thesame.

v To all whom it may concern Be it known that I, DWIGHT SLATE, of thecity and county of Hartford, and State of Connecticut, have inventedcertain new and useful Improvements in Shipping Apparatus for PlaningMachines; and to enable others skilled in the art to make and use thesame, I will proceed to describe, by referring to the drawings, -inwhich the same letters indicate like parts in each of the figures.

The nature of this invention will be understood from the specificationand drawings, the object of which is to simplify and make more directthe action of the whole mechanism ofthe shipping-apparatus of a planer.

It has heretofore been the most dicult part to arrange in a planer,involving many joints, rods, &c.

By this arrangement, many parts heretofore used, are dispensed with, bysubstituting a rock-shaft, or a rolling, or oscillating cam, securedupon a rock-shaft, which carries or actuates the shipper-rod,therebyrendering it more simple, eliicient, and durable.

In the accompanying drawings- A is a shipper-block, fitted to theprojecting edge E of the planer-frame, G, so as to traverse back andforth thereon, and is actuated by the common stops, secured upon theside or edge of the bed B.

C is a friction-roller or pin, secured in the block A, directly over,and works in, a zigzag, or spiral groove D, formed in the rolling, oroscillating cam E, which is secured upon the shaft F, that actuates,through the arm, or segment-gear J, which works in a toothed rack, onthe reciprocating-shaft K, the belt-guides I, and thereby changes themotion of the driving-wheels from one direction'to the other, thusrendering the action, simple, direct, and positive, and easy to beadjusted, and not liable to get out of order.

I do not wish to limit myself to the particular arrangement of the camE, because it may be used, under various modifications of arrangement,relatively to the parts acting in connection therewith.

I do not claim a metal-planer, nor do I claim broadly, a shipper-device,for producing areciprocatiug or changemotion of a planer-bed.

I believe I have thus shown and described the nature, construction, andadvantage of this invention, so as to enable others skilled in the artto make and use the same therefrom.

Y What I claim, and desire to secure by Letters Pat ent, is

'lhe oamE, sliding-block A, in their relation to thereciprocating-planer-bed B, through the stops A', and in combinationwith the rock-shaft F, arms or segmentgear J, transverse sliding-shaftK, and shipper-arms I, substantially as and for the purpose described.
